APPARATUS FOR THE FILLING 0F TUBES.

Specification of Letters Patent.

Patented May 21, 1912.

Application filed une 10, 1911. Serial No. 632,514.

To all whom it may concern.-

Be it known that I, ALBERT J onenN KIER, mechanical engineer, subject of the Kingdom of Denmark, residing at No. 8 Alleegade, in the city of Copenhagen, Denmark, have invented new and useful Improvements in Apparatus for the Filling of Tubes, of which the following is a specification.

The invention has for its object an apparatus for filling tubes with pastes as toothpaste, shoe-blackings and the like, by which apparatus is obtained that the tubes can be filled quickly and cleanly with exactly measured quantities.

Figure 1 shows the apparatus seen from above and Fig. 2 the apparatus in side view.

A reservoir 12 containing the paste to be filled in tubes is fixed to a base-plate a. A supply tube a passing across the reservoir near the bottom of the same is fixed to said reservoir. Inside the reservoir the upper part of said supply tube is cut away to form a large opening d (Fig. 1) through which the paste can be sup-plied to the interior of the supply tube 0. A measuring tube e having a sharp edge fits into the supply tube 0. The measurlng tube 6 can be moved in the supply tube 0 thereby cutting ofi' a cylindrical piece of the paste. The measuring tube e is provided with an ejector piston f and is carried by a hollow rod 9, which can be reciprocated by means of a lever h. The rod 70 of the ejector iston 7 passes through said hollow rod an can be moved by means of the lever m. A suitable guide n causes the rods 70 and g to move in a straight line. The 0p osite end of the supply tube 0 is connected to a cylinder 0 provided with a piston g, which is acted upon by a spring 12. In the side of said cylinder 0 is an opening corresponding with a mouthpiece inserted upon the cylinder. The tubes which are to be filled are inserted upon said mouth-piece which can be changed in order to correspond with different shapes and sizes of the tubes. The movements of the levers h and m are such, that the lever it can be moved to the left independent of the lever m, while the latter, when both levers have been'moved to the left, is returned by the lever h, when said lever is moved to the right. The 'lever m can be locked in its outermost right position by a suitable spring-lock t, which can be released by a pressure upon the button a (Fig. 2). The levers h and mare not shown in Fig.

2, in which figure the crosshead '2; of the piston-rod 7c is shown in section.

The operation of the apparatus shall now be described.

It is assumed that the reservoir b is filled with paste which also through the opening a? fills that part of the supply tube 0, which is inside said reservoir. An empty tube is inserted upon the mouth-piece 1*. Then the measuring tube e is moved to the left by means of the lever it, while the ejector piston f remains in the position shown; its pistonrod 70 being locked by the spring-lock Z. By this movement the measuring tube 6 cuts off a cylindrical piece of the paste of such a quantity to exactly fill a tube, and when the edge of the measuring tube e has passed the left end of the opening (Z, the measuring tube e closes said opening toward the interior of the reservoir I). Then the springlock t is released by pressing down the button u, and by means of the lever m the ejector piston f is moved to the left thereby pressing the paste inclosed in the measuring tube 6 against the piston g, which latter yields and opens the port leading to the mouth-piece 1". Of course the paste will be forced out through the mouth-piece and fill the tube inserted upon it. When the tube is filled the lever h is moved to the right thereby returning lever m, measuring tube 6 and ejector piston f to initial position, while the spring p and the pressure of the atmosphere will return the piston g to the position in which it closes the port leading to the mouth piece 1'. When the measuring tube 6 is returned to its initial position it leaves a vacuum in the supply tube e which causes the paste in the reservoir 1) which is under atmospheric pressure to be pressed down through the opening cl. When levers h and we have been returned to initial position the piston-rod la is again locked and a fresh tube is inserted upon the mouth-piece r whereupon the operations can be repeated in the same order.

The constructional form of the apparatus shown in the drawing may be altered without departing from the principle of the invention.

Claims:

1. In apparatus for filling tubes with a measured quantity of paste or the like, the combination of a paste reservoir, a supply tube passing across the reservoir near the bottom of and through opposite walls of the same, a supply opening being provided in the upper part of said supply tube and a port being provided at one end of the supply tube, a movable measuring tube fitting into said supply tube, an ejector piston in the measuring tube, a delivery mouth-piece connected with said port at one end of the supply tube, movable means for normally closing the port leading to said mouth piece, means for independently moving said measuring tube through said supply tube and means for independently moving said ejector piston toward the port closing means, substantially as described.

2. In apparatus for filling tubes With a measured quantity of paste or the like, the combination of a paste reservoir, a supply tube passing across the reservoir near the bottom of and through opposite walls of the same, said supply tube being provided with a supply opening in the upper part thereof,

a movable measuring tube fitting into said supply tube, an ejector piston in the measuring tube, a cylinder connected withone end of said sup-ply tube and provided with a port, a delivery mouth-piece provided on said cylinder for said port, a spring controlled piston arranged in said cylinder and normally closing the port leading to said mouth-piece, means for independently movl ing said measuring tube through said supsaid sup-ply tube being provided with a' supply opening in the upper part thereof, a movable measuring tube provided with an ejector piston and fitting into said supply tube, a delivery mouth piece connected with said port at one end of said supply tube, movable means, which normally close said port, levers for moving the supply tube and the ejector piston respectively toward the port leading to the mouth piece and means for locking the lever, which operates the ejector piston, in its initial position.

In testimony whereof, I ALBERT Joneniv KIER have signed my name to this specification in the presence of two subscribing witnesses, this 30th day of May 1911.
